A recent article in
the Journal of Pediatrics (1) stated
that 1 in 10 parents do not completely vaccinate their kids. The MMR vaccine
was cited as the vaccine withheld most frequently. This is most likely due to
the infamous 1998 manuscript in The Lancet
stating that there is a “link” between the MMR vaccine and autism. Though the
original manuscript has since been retracted from The Lancet due to falsified data, its effects are still lingering. There
are children out there that are not getting vaccinated due to this bad science.
Bad science does
not just impact researchers’ understanding; it impacts people’s lives. This
study illustrates what can happen when articles are published, but are then retracted
after a larger audience has vetted the ideas therein.
I wish I could say
that retractions are a relatively rare occurrence. Sadly, this is not the case.
A website called Retraction Watch publishes cases like this on a very regular basis. Retractions are
posted from journals across the scientific gamut. You might be thinking that
only minor journals, with a low impact factor, would be the major culprits. This is most definitely not the case. Major
journals like Nature and Science are featured frequently.
The interesting
thing is that the scientific community always vilifies the authors. However,
there is no real outcry against journals publishing, then retracting, articles
with spurious findings.
This is wrong.
There should clearly
be some blame passed to the journal publishing the manuscript.
This goes back to
one of our guiding principles at OSK: transparency.
The scientist’s
book of holy writ is the peer-reviewed journal; once an article is published in
a journal, it then, in essence, becomes “canonized”. However, there is no real
discussion about the merits and flaws of this system. We need to take a deeper
look into what actually constitutes peer-reviewed publishing. We need to ask
ourselves if there is a better way to do this and why we did not seek it in the
midst of obvious flaws in our publishing system.
Currently all publication
requires is an “okay” from a handful of peers. Similarly, a handful of “not
okay”’s can condemn an article to rejection. This small number of reviewers
leaves open the possibility of numerous biases; we rigorously test for these
biases in statistical analysis, but never inquire about them in peer review. We
similarly never inquire about the possibility of dissent among reviewers,
leaving our faith in the journal to give us only manuscripts that are
unquestionably of the highest quality.
This whole process
needs to be turned on its head. Most directly, we must include more reviewers
in peer review. Dissenting reviews should be provided for the reader, as they
offer an important tool with which to understand the context of a published
manuscript. Probably more importantly, all data used to make conclusions should
be subject to review, as it is fundamental to the validity of a manuscript.
Limitations must be emphasized, as they are the most important part of any
manuscript!
Once these solutions
are implemented, the retraction rate will decrease. Ultimately, this will impact
not only the researchers, rewarding truly high-quality research, but also the
people their research is likely to affect.

Being a soon to be parent, I have a better understanding of the intricacies related to these studies affecting new parents. It’s really scary to begin with, then an added confusion on top of that stemming from patients trusting doctors(which I whole heartedly believe we should do). If one doctor shows one result, ie vaccines cause autism, and another shows the opposite, who do you trust?
ReplyDeleteI believe this step is a crucial point at which peer review holds the most meaning. Peer reviewers need to let everyone else know who to trust and it needs to be done right the first time with as you say, transparency. People need the confirmation from peer reviewers and the ability to do their own quick review of the information comparing good sides and bad. There seems to be a connection at this point in my mind with informed consent. A doctor needs to explain risks and benefits, complications, outcomes, etc. with a patient. This process may only take several minutes but needs to be there to insure the best standard and quality of care for the patient. Why don’t we have “informed consent” for these studies in the form of open peer review where all the strengths, benefits, faults, risks and limitations are brought into the open just as doctors explain these items before a procedure or treatment? After all, the patients are the ones experiencing the results whether it is from the immediate procedure or the results of comprehensive, cohort studies performed at far off institutions.
